Large food companies and international packaging buyers rarely select a supplier from a product photo alone. They need confidence that the supplier can repeat the same specification, provide clear documents, manage changes and communicate when a problem appears.
The review process may begin with a PET jar, bakery tray or PP food tray, but it usually expands into a broader evaluation of factory capability, quality systems, samples, traceability and delivery planning.
1. Product and Process Fit
The supplier should understand the buyer’s application and identify the correct production route. A PET jar project may involve injection molding, closure coordination, labeling and filling review. A PP tray project may involve PP sheet extrusion, thermoforming, trimming, inspection and outer packing.
A buyer should ask which parts of the process are performed by the factory, which materials are sourced externally and which specifications are controlled at each stage. Clear answers help prevent misunderstandings later.
2. Material and Specification Control
International buyers normally expect the supplier to identify the exact model, material, dimensions, weight, capacity, component structure and intended application. The approved specification should be linked to the sample and quotation.
For thermoformed packaging, the buyer may also review sheet material, thickness, forming design and trimming. For PET jars, the buyer may review the jar body, opening, closure and decoration. The selected documents should match the product being purchased.
3. Sample Approval
A sample is a decision gate. It allows the buyer to check product fit, appearance, dimensions, closure or cover interaction, labels, stacking and outer packing. A serious program should record the approved sample and any changes.
When a buyer has several SKUs, the same process should be applied to each model. Similar model names or images do not prove identical specifications.
4. Quality Systems and Records
A factory review may cover raw material receiving, production environment, equipment management, process inspection, finished-product inspection, batch records, traceability and non-conforming product handling.
TIMES Plastic operates documented BRC, ISO 9001 and ISO 22000 quality systems. Current certificate details and their applicable scope should be reviewed against the buyer’s requirements. Quality language should be tied to evidence rather than broad marketing claims.
5. Production and Packing Capability
A supplier should explain how it manages production scheduling, inspection, carton packing and repeat orders. Buyers may also need information about tooling, artwork, sample timing, MOQ and production lead time.
TIMES Plastic supports PET jars and PP/PET thermoformed packaging through injection molding, PP sheet extrusion, thermoforming, sampling, quality control and an in-house printing workshop. The specific capabilities available depend on the selected product and approved project scope.
6. Communication and Change Control
A stable supplier relationship depends on clear communication. When a buyer changes the drawing, material, artwork, quantity or packing method, the supplier should identify the effect on tooling, sampling, price and schedule before production.
This is especially important for global food brands and international distributors managing several product sizes or markets. A written specification and approval record helps both sides keep the project aligned.

FAQ
Do large food companies only check the product price?
No. They commonly review product fit, specification control, quality systems, samples, traceability, packing, communication and supply planning.
Why is traceability important?
It helps connect a finished product to its production and inspection records, making repeat orders and issue investigation more manageable.
Can an anonymous supplier case study be used on a website?
A company may describe general buyer requirements without naming the customer, but it should not invent order volumes, project results or identifiable details.
What documents should a buyer request first?
Start with the technical drawing, material information, approved sample record, applicable certificates, inspection information, packing details and commercial quotation.
How can a supplier prepare for an international buyer review?
Maintain clear procedures, current documents, consistent records, sample approval, batch traceability and a defined process for handling changes and non-conforming products.
